williams180 is correct, though insulting intelligence usually doesn't convince someone. There are plenty of "smart" people that still manage to vote for Howard and plenty of "dumb" who vote for Labor.
The 3 reasons I've heard for people voting liberal so far are:
1) Oh, I've heard of that Howard guy, I think I seen him on da news.
2) He'll keep the fags out.
3) Interest rates have been lowest with Howard.
#1 & #2 people should NOT have the right to vote. #3 are severely mislead and wouldn't know the first thing about economics.
Oh and remember the Howard promise: No GST, no children overboard, absolutely no interest rate rises, which will be at all time lows. Yep, you know that you can trust eyebrows.
