John McCain is a thorn in the side of conservatives.

He conspires with Democrats and sabotages Donald Trump’s agenda.

And he just hurled a jaw dropping insult at Trump that should spell the end of his career.

McCain is continuing to act as a one-man wrecking crew against Donald Trump and the Republican voters who sent him to the White House.

It wasn’t enough that McCain revealed himself to be a liar when he campaigned on repealing Obamacare only to cast the deciding vote to kill the legislation that would have gutted the law.

Now he’s throwing insults at the President with cheers from the liberal media.

In a C-SPAN interview about the Vietnam War, McCain smeared Trump as a draft dodger and borderline traitor.

The Washington Post lapped up McCain’s attack and gleefully wrote that he “hits Trump where it hurts.”

After a week in which President Trump endured not-so-veiled criticisms from his two predecessors as president and Sen. John McCain (R-Ariz.), McCain delivered another broadside that seems clearly aimed at Trump — in the most personal terms yet.

McCain, whose status as a war hero Trump publicly and controversially doubted as a 2016 presidential candidate, appeared to retaliate in kind against the president in a C-SPAN interview about the Vietnam War airing Sunday night. In the interview, McCain pointed to wealthy Americans who were able to get out of being drafted into service in the conflict in which he spent years as a prisoner of war. And he pointed to a very specific type of deferment which Trump just happened to use.

“One aspect of the conflict, by the way, that I will never ever countenance is that we drafted the lowest-income level of America, and the highest-income level found a doctor that would say that they had a bone spur,” McCain said. “That is wrong. That is wrong. If we are going to ask every American to serve, every American should serve.”

But Trump was not cleared to serve after he reported for a physical in 1968 and the doctor declared him not qualified for battle.

McCain’s insult to Trump was the final straw for many Republicans.

The Arizona Senator has consistently stabbed his own party and President in the back in order to suck up to the liberal media.

It’s an act that has worn very thin.

Whose side are you on in this fight – John McCain’s or Donald Trump’s?
