The weekend blitz is about to begin in the 11th Congressional District as the forces of Democratic incumbent Rep. Jerry McNerney and GOP nominee David Harmer converge on the district.

This is one of 50 or more congressional seats in the country that could flip parties and put the GOP in charge of the House of Representatives, and both sides can taste victory.

Your doorbell may ring. Your mailbox will fill up. Your doorknob may be festooned. A candidate or his proxy may show up at your house. And your radio and TV stations will blare with the latest advertising, much of it featuring wildly distorted and unreliable information.

California unions are gearing up for major precinct work this weekend as they push to get Democrats to the polls in support of their candidates from the top of the ticket on down to the local races.
