What I don't agree with though is the assertion that Rand Paul is doing what he is doing in order to suck up to the party and political elites.
I too disagree with that assessment. Rand's not "sucking up" to the party elites in the sense that he's compromising his principles (as is evident from his stellar voting record). He
is trying not to gratuitously insult them, and work with them when possible. This makes him more effective as an advocate for liberty, not less effective.
The party elites are by and large not anti-libertarian, in the sense that they have some deeply felt animosity toward our principles. They're mostly unprincipled altogether, and just want to get reelected and retain/augment their power. We can work with people like that at times E.G. If McConnell wants Rand to campaign for other Senators, in exchange for McConnell using his influence in KY to help Rand get on the POTUS ballot (as actually happened this past year), there's nothing wrong with that. That helps us.
I like his voting record but what I do question his tactics. As the candidacy of Donald Trump is showing being perceived as giving the finger to the man can be good politics, it is shame that Trumps policies aren't as good as his tactics.
Trump isn't a sitting Senator. He can insult the party bosses without consequence. Rand can't.
In any event, Rand's tactics were working just fine until the political narrative changed.
...all of the sudden we went from "libertarian moment" to "Messicuns r rapists!"
He was leading in the polls for a while, and was clearly on the path to being the "anti-establishment" alternative to Jeb/whoever this cycle.
I don't think there's anything fundamentally wrong with Rand's strategy; events outside his control ruined things this cycle.
We'll have to see what the landscape looks like in two years before we can say how Rand should play it next time.
Maybe he should continue doing what he's doing, maybe he should make a theatrical break with the party elite, ala Trump.
Which strategy is best depends on the situation.
