How big could the Scott Walker scandal be?

This is a guest post by Brandon Rottinghaus, Senator Don Henderson Scholar and Associate Professor in the Department of Political Science at the University of Houston.

Wisconsin Gov. Scott Walker could be in legal hot water. Prosecutors claim that Walker was at the “center of a scheme to violate campaign law by improperly coordinating campaign activities with outside groups.” Given his rising political position in the Republican Party, a reelection bid in Wisconsin in November and a prospective presidential candidacy in 2016, what might this scandal do to his political and electoral prospects? Here are key questions:

Will this hurt him in the 2014 election?

 Given the allegations: yes.

Although there is little work on gubernatorial scandal as it relates to elections, the approval ratings of most politicians are hurt by scandal. For elections in the House of Representatives, Praino, Stockemer and Moscardelli found that members of Congress who had one or more of their actions referred to the House Ethics Committee were less likely to be reelected (49 percent) than those Members who did not have a case referred (87 percent). The specific type of scandal may matter also: corruption scandals led to an 8 percent reduction in vote share among Member of the House of Representatives while sex and financial scandals led to a 5 percent reduction in vote share.

Because of the alleged political collusion in this case and a very close election, this scandal may absolutely shrink enough support for Walker to lose the election.

Could he lose his governorship in the meantime?

Likely not, short of bombshell criminal charges filed forcing him to resign.

In a recent article, I charted the duration of gubernatorial scandals from 1972 to 2011 and examined the factors that ended an official’s career more quickly.

First, elected officials themselves (as opposed to appointees, nominees  or staff) are more likely to survive a scandal. This is especially true for governors, which is good news for Walker.

Second, as opposed to other kinds of scandals (sexual, etc.), political scandals like Walker’s are harder to prove and don’t affect the survival of the governors involved in them.

Third, the more legislative opposition, the less the chance of surviving scandal. In this case, Wisconsin law requires two-thirds of the State Assembly to impeach and a majority of the state Senate to remove the governor from power. Since the Republican Party controls 60 percent of the State Assembly and 55 percent of the State Senate, Walker has a cushion.

Will this affect his presidential prospects?

Even if he survives in Wisconsin, keeps his position and wins reelection, the evidence suggests that his putative presidential campaign may take a hit, especially among his supporters.

In another article, using scandals connected to non-incumbent presidential aspirants from 1996 to 2012, I tracked the effect of each scandal on each campaign’s daily fundraising totals, competitive standing in the race and party endorsements.

Scandals involving Republican presidential candidates tended to be more damaging than for Democrats, especially in terms of fundraising and endorsements. For example, Republican candidates lose between one and two endorsements per day when a scandal is associated with the campaign.

The wide-open competition for the 2016 Republican presidential nomination is sure to produce many candidates, some viable and some not. A candidate hobbled by scandal may be late out of the starting gate and find him or herself lagging behind.

The New Hampshire primary is Tuesday. Get caught up on the race.
The Post's Dan Balz says ...
This was supposed to be the strongest Republican presidential field in memory, but cracks are showing. At Saturday night's debate, Marco Rubio withered in the face of unyielding attacks from Chris Christie, drawing attention to the biggest question about his candidacy: Is he ready to be president? How much the debate will affect Rubio's standing Tuesday is anybody's guess. But even if he does well, the question about his readiness to serve as president and to go up against Clinton, if she is the Democratic nominee, will linger.

New Hampshire polling averages
A victory in New Hampshire revitalized Hillary Clinton's demoralized campaign in 2008. But this time, she's trailing Bernie Sanders, from neighboring Vermont. She left the state Sunday to go to Flint, Mich., where a cost-saving decision led to poisonous levels of lead in the water of the poor, heavily black, rust-belt city.
