seeing red

The election is on January 23. Today, driving through my neighbourhood, I saw plenty of red Liberal election signs. Are these people not ashamed to put up a Liberal sign and vote for a party that is mired in scandal and corruption, that has embezzled millions of tax dollars, that has ridden roughshod over the electorate time and time again, broken promises, screwed up every file on the agenda and hung on to power through chicanery and unsavoury machinations?

As far as I know, most ridings have at least four candidates, some as many as eight: vote NDP, vote Conservative, vote Green, vote Communist, for chrissakes - but why on God's good earth would you vote for these crooks again? If someone can truly, truly help me understand it, I'd be grateful.
