Sorry, while editing my post I ended up with a ridiculous-looking sentence (obviously all 3000 of those tweets weren't about Obamacare). It looks like at this point he's deleted almost all of his history all the way up through ~November 16th. At the time though it looked like it was just a block of tweets[1], which happened to include a couple of his most popular tweets ever (including the one screenshotted above about Obamacare). The timing of the original deletions was at the same time news was coming out about big premium increases under Obamacare next year, which is where the link between the tweet deletions and Obamacare came from. That may have just been a coincidence, though. It doesn't take away from the fact that he doesn't stand by the opinions he spews to 200k followers.
You can see in the 2nd link is my previous post that someone caught a screenshot of a tweet-deleter app spamming his timeline (this was in late October, I also saw those tweets in real-time), which means he's done another round of cleansing, basically deleting his entire tweet history.
