Monday, this year's deadline for filing federal and state taxes, is going political.

Two South Carolina groups -- on opposite ends of the political spectrum -- have announced tax rallies in Columbia. Members of the Columbia Tea Party, which advocates for more limited government and lower taxes, will host their biggest rally of the year at the State House.

The lineup includes potential presidential contender U.S. Rep. Michele Bachmann, R-Minn., and S.C. Gov. Nikki Haley. Other Tea Party favorites --including state Sen. Tom Davis, R-Beaufort, and state Treasurer Curtis Loftis -- also will speak.

Bachmann, already scheduled to be in the state, asked the Tea Party if she could be included in its rally.

MoveOn.org, a national progressive political action committee, and other organizations will host a protest outside Bank of America on Columbia's Main Street on Monday, urging the bank to pay, what the group calls, its fair share of taxes.

It is part of a nationwide Tax Day campaign called "Make Them Pay" that is targeting large corporations, including Google, BP and Citigroup, that paid little or no corporate income tax in recent years. Some of the financial groups received federal bailout money in 2008 to stay afloat, including Bank of America.
