Politics can be a fickle endeavor. Your enemy becomes your friend at times for the most dubious of reasons.

History is full of such examples: John F. Kennedy and Lyndon Johnson battled for the Democratic nomination in 1960; JFK then picked LBJ as his vice president. George H.W. Bush accused Ronald Reagan was espousing “voodoo economics” in 1980; then the Gipper picked Poppy to be his No. 2. Barack Obama told Hillary Clinton she was “likable enough” during a 2008 Democratic primary debate; then Obama tapped Clinton to serve as secretary of state.

Now we have Ted Cruz, the Republican senator from Texas — the guy who called Donald J. Trump a “pathological liar,” a “serial philanderer,” and an “amoral bully” — endorsing the GOP presidential nominee.

The Cruz Missile is going to vote for Trump in November, he said. Why the change of heart? It looks for all the world like an anti-Hillary endorsement.

Frankly, I thought Cruz might withhold his endorsement throughout the campaign, given the hideous things Trump said about the senator, his wife Heidi and his father. It got intensely personal for Cruz and I believed he was right at the GOP convention to urge the delegates to “vote your conscience.”

Well, it didn’t happen.

The fickle nature of politics has shown once again how foes can set aside hurtful comments to achieve a common end.

Will it help or hurt? Many of Cruz’s most ardent conservative supporters believe Trump is an imposter to their principles.

What the heck. Politics in this raw form can be downright ugly.
