Independent voters are most likely to have heard of Twitter, according to a new poll released Thursday, while there is little difference in party affiliation for users of the microblogging site.

A Hotline/Diageo poll released Thursday found that 62 percent of Independents have heard of Twitter, compared to 55 percent of Republicans and 53 percent of Democrats.

When it comes to actually using the site, though, four percent of all those surveyed said they use the site. Five percent of Democrats, four percent of Independents, and three percent of Republicans use Twitter.

Strong minorities in each category told pollsters they had never heard of or used Twitter, including 41 percent of Republicans, 42 percent of Democrats, and 34 percent of Independents.

The Hotline/Diageo poll, conducted Mar. 26-29, has a 3.5 percent margin of error.

Sen. Jim DeMint (R-S.C.) is among the senators participating in today's "vote-a-rama" in the Senate, though he has a bit of a stake in today's votes.

DeMint invited his Twitter followers to "stay tuned" today, as he offers amendments on a number of issues, ranging from the budget to bailouts.

DeMint tweeted:

Stay tuned for "vote-a-rama", dozens of budget amdt votes today, I'll have many including one to end the auto bailouts

Earlier, Sen. Claire McCaskill (D-Mo.) previewed the marathon of votes, referring to the name "voterame" (as she spelled it) as "dumb."

The Washington Post's Chris Cillizza ("The Fix") may be tweeting a bit too much for his own good, judging by one post on his Twitter stream this morning.

Cillizza wrote:

Woke up in the middle of night with a great tweet. Fell asleep. Woke up this morning and can't remember it. This keeps happening.

Of course, Cillizza tweets with more gusto than most other journalists on the microblogging website. In addition to his eponymous "The Fix" twitter page, Cillizza also maintains "The Hyper Fix," in which he live-tweets White House press briefings and other major news events.

Conservative pundit Michelle Malkin took it to 10 House Republicans who voted last night for a bill to curb executive compensation, with one of those lawmakers hitting back via Twitter.

Last night Malkin tweeted:

Ugh. Meet the 10 House Republicans for arbitrary salary control. Posted roll call vote breakdown

But Rohrabacher, one of the 10 Republicans to have voted for the bill, tweeted back.

Rohrabacher first tweeted:

@michellemalkin It isn't the "Pay 4 Perform Act" it's "If the taxpayers pick up the bill the corp bosses can't run away w/the loot act"

The California Republican then followed up:

@michellemalkin This legis only affects companies that receive gov't bailouts, there should be restrictions when taxpayer $ is given away

Rohabacher then added:

@michellemalkin Those who've brought down their own company shouldn't be permitted to enrich themselves at the taxpayers' expense.

Malkin then tweeted back:

@DanaRohrabacher Don't give them our money in the 1st place! Problem solved.

But Rohrabacher got the last word, in two consecutive tweets. First:

@michellemalkin I agree, unlike some of my now self righteous Republican colleagues I've voted against every bailout from day one.

And then:

@michellemalkin We seem to disagree whether there should be preconditions if a private company is bailed out by the taxapayers.

UPDATE: Malkin carried the entire debate to her blog, which you can read through here.
