It doesn’t matter that Sen. Ted Cruz (R-Tex.) was a condescending jerk in law school who thought he was the smartest guy in every room. It matters whether he grew out of it and whether he’s left a long trail of peers and staff who’ve been treated badly by him, evidencing poor character.

It doesn’t matter if there are 41 votes to filibuster the House continuing resolution (CR) that Cruz demanded from the House. What matters is, if you do the math, there aren’t 51 votes or 66 to override a veto to pass a defunding CR.

It doesn’t matter that Jim DeMint and the same small band of right-wingers favor a shutdown. What matters is that by a 59 to 19 percent margin, Americans oppose it and a large plurality (48 percent) of Republican oppose it.

It doesn’t matter if Cruz and Sen. John McCain (R-Ariz.) don’t get along. It matters if his obnoxious behavior now leaves him with few allies and makes him incapable of accomplishing anything other than his own self-promotion.

It doesn’t matter that Cruz keeps calling it “defunding.” What matters is even in a government shutdown, Obamacare marches on (along with other entitlements).

It doesn’t matter what Sen. Marco Rubio (R-Fla.) does at this point. What matters is he looks like the younger brother conned into a reckless prank by savvier players.

It doesn’t matter how Cruz loses this fight. It matters that he defined victory as defunding Obamacare and if he doesn’t deliver it will be clear even to the most oblivious conservatives that the whole thing has been a fraud.

It doesn’t matter who is blamed this week. What matters is that the Obamacare battle was lost (for now) in the 2010 and 2012 elections, leaving the GOP controlling only the House.
