Neither of the three are worth voting for...so what you see is a public who is voting against Brown mostly...and hoping for a change in British politics.
If this were a wager situation...I’d bet on a second election and similar results. By the third election (which is possible), Brown would step aside and Labor would toss in a new candidate and possibly win. Cameron reminds me of McCain in a way...alot of talk but no real substance.
