You are entitled to your opinion on why he sponsored the earmark bill, however, you have zero proof to back up your claim.

As a matter of accuracy, the proposed earmark legislation bill was voted against by 59 senators. Of those who voted against it,13 were Republicans and 46 were Democrats. Thus your claim that his own party rejected his earmark bill is, again, inaccurate.

33 Republicans for the bill as did 7 Democrats.
