Campaigns are a reflection of the candidate:

CLEVELAND, Ohio — Republican nominee Mitt Romney's guerrilla tactics continued Thursday, as the campaign bus circled the venue where President Barack Obama will be speaking this afternoon.

As it passed the assembled throngs of supporters awaiting entry to the event at Cuyahoga Community College, the bus honked its horn dozens of times, before circling around to do it again. Obama supporters jeered and booed each time the bus passed the line outside of the security screening area.

Is this "presidential"?

Josh Marshall adds:

This is actually a core part of the Romney camp’s election strategy.

Remember, this isn’t the first time something like this happened. A few weeks ago the Romney camp sent staffers to disrupt a press conference that Obama campaign strategist David Axelrod held in Boston to trash Romney. And that came just after the Romney camp darkly hinted that the Obama team had been conspiring to disrupt or block the event it held in front of the shuttered doors of Solyndra.

It all sounds kind of weird and erratic. But it’s not. Or at least it’s not accidental.

The Romney camp has made a straightforward calculation that it can make up with appeals to the conservative id the ground it can’t ever make up convincing anyone that Romney is really a right-wing ideologue.

At one level this is simply another illustration of the “bitch slap” politics which rumbles beneath so much of presidential politics. And of course emotion always plays a big role in each side’s take on the political opposition. But the animus against President Obama isn’t just tied to his positions. There’s a deeply rooted sense on the right that Obama has been protected, coddled — that no one has really taken it to him in a down and dirty way. This is what’s behind the talk that he never got ‘vetted’ back in 2008. And if you remember back in the primary debates, there was a recurring theme of which contender was the guy who could really bring the full primal scream mojo to Obama at the debates. Not so much even which guy could beat Obama but which would have the cajones (and I use that term advisedly) to hit him with the full socialist-African-terrorist-lovin’-debt-meister smackdown that would somehow just leave a shattered Obama grasping blindly for his teleprompter.

The Romney folks know that pretty much nobody — not the Republican base or really anyone else — is going to be convinced that the candidate is a down-the-line conservative. But he can appeal to them by playing the bad ass card, getting in Obama’s grill, disrespecting him. Not in highly public ways and not the candidate himself — that could be damaging. But in slightly out of the way ways, the sort of stuff that really committed political types do see.

In other words, expect to see a lot more of this.
