ALBANY - Running for re-election cost Albany Mayor Kathy Sheehan just shy of half a million dollars.The latest state campaign finance filings show Sheehan loaned her campaign a total of $482,000 for her re-election bid, including loaning herself another $95,000 in late December.The high price tag on running for office bolsters the perception that politics favors the rich and the well-connected and prompts further calls for campaign finance reform.
