Mica was attacked for supporting the proposal in his neighboring state by his opponent in a contentious member-versus-member primary, Rep. Sandy Adams.
The proposal to raise sales taxes in Georgia to fund infrastructure improvements split traditional alliances in both the Democratic and Republican parties. Business groups that normally endorse GOP candidates vocally supported the proposal, while Tea Party groups rallied against the idea of raising taxes.
Similarly, Democratic Atlanta Mayor Kasim Reed, a frequent surrogate for President Obama's reelection campaign, clashed frequently with NAACP groups in the Atlanta area that argued that the measure did not include enough spending in traditionally African-American areas.
The reliably Democratic metro Atlanta area had been expected to provide a base of support for the transportation tax. However, the measure was defeated 63-37 percent in the 10-county region that included the Georgia capital city.
Supporters said the levy would have provided $18 billion
for road and transit projects in the state, with $6.1 billion going to the
metro Atlanta area.
