Casey goes after Facebook co-founder

US Sen Bob Casey is going after a Facebook co-founder for his plans to renounce his US citizenship just before the social media giant goes public.

Calling the plans by Eduardo Saverin an "outrage," Casey and fellow Democrat Chuck Schumer are holding a press conference at 11 a.m. today in which they'll unveil a plan to to "re-impose taxes on expatriates like Saverin even after they flee the United States and take up residence in a foreign country. Their plan would also bar individuals like Saverin from reentering the country." (WSJ)

Speaking of Casey, NYT poll expert Nate Silver writes that Casey's reelection this year should be safe. Here's his reasoning:

Republicans were in need of a strong candidate to seriously challenge the Democratic incumbent, Bob Casey, who is fairly popular. Instead, their field failed to coalesce and they picked an inexperienced nominee, the businessman Tom Smith, in their primary in April. We classify the race as Safe Democrat, rather than Likely Democrat as before.
