President Obama easily won Texas’ Democratic presidential primary Tuesday, ending a streak of surprisingly close races against little-known challengers.

With 82 percent of precincts reporting, Obama is winning 88 percent of the vote.

John Wolfe, a Tennessee lawyer who took 42 percent of the vote in Arkansas’ Democratic primary, so far is winning only 5 percent in Texas. Florida author Darcy Richardson has 4 percent; Chicago investor Bob Ely is at 2 percent.

Obama has fared poorly recently in Democratic primaries in Arkansas, Kentucky and West Virginia, losing large votes shares to longshot challengers. But while all four states tend to vote Republican, Texas is not like the other three.

Texas is more urban and racially diverse, and the Republican Party has already captured most voters who would be inclined to oppose Obama from the right.

As Democratic strategist Matt Angle told The Fix earlier today, “In Texas, the people who don’t like Obama vote in the Republican primary.”
