Look at the linked comparison below, of Obama and Romney campaigns' funds raised, and cash on hand, as of the end of March.

With Obama having raised $196,900,097 and having 10 times more cash on hand than Romney at that point, how would anyone expect Romney (or anyone in that opponent position) to not try to raise an equal amount of money??????

Fundraising is usually a candidate's least favorite activity/work. They do this kind of fundraising because they have to, to compete!
