One of the many forms of conventional wisdom in the wake of the 2014 mid-term election goes something like this: Republicans, flush with victory at taking over the Senate and expanding their hold in the House, now face a fight between the tea party extremists and the mainstream wing of their party.

Let’s go with that one for a moment, maybe two.

I relish the thought, to be brutally candid.

The likely Senate majority leader, Mitch McConnell of Kentucky, may be looking over his shoulder at one of the tea party upstarts within his Republican caucus, a fellow named Ted Cruz of Texas.

Cruz wants to lead the party to the extreme right. McConnell is more of a dealmaker, someone who’s been known to actually seek advice and counsel from his old friend and former colleague, Vice President Joe Biden. Cruz, who’s still green to the ways of Washington, wants to shake the place up, seeking to govern in a scorched-Earth kind of way. He wouldn’t mind shutting down the government again if the right issue arises. McConnell won’t have any of that.

So, will the battle commence soon after the next Congress takes over in 2015.

Lessons unlearned doom those who ignore them.

Republicans have been through this kind of intraparty strife before. In 1964, conservatives took control of the GOP after fighting with the establishment. The party nominated Sen. Barry Goldwater as its presidential candidate and then Goldwater got thumped like a drum by President Lyndon Johnson.

They did it again in 1976, with conservative former California Gov. Ronald Reagan challenging President Ford for his party’s nomination. Ford beat back the challenge, but then lost his bid for election to Jimmy Carter.

To be fair, Democrats have fallen victim to the same kind of political cannibalism.

In 1968 and again in 1972, Democrats fought with each over how, or whether, to end the Vietnam War. Sens. Robert Kennedy and Eugene McCarthy challenged LBJ for the nomination in 1968. Johnson dropped out of the race, RFK was assassinated, McCarthy soldiered on to the convention, which erupted in violence and Democrats then nominated Vice President Hubert Humphrey, who then went on to lose to GOP nominee Richard Nixon.

Four years later, the Democratic insurgents nominated Sen. George McGovern after fighting with the party “hawks.” McGovern then lost to President Nixon in a landslide.

So, what’s the lesson?

History has shown — and it goes back a lot farther than just 1964 — that intraparty squabbles quite often don’t make for a stronger party, but a weaker one.

Bring it on, Republicans!
