UKIP is poised to win its second parliamentary seat on November 20, taking votes from Britain's Prime Minister David Cameron's Conservatives six months before a national election. Once dismissed by Cameron as "closet racists", UKIP has poached two of his lawmakers in recent months and won its first seat in Britain's parliament in October, at his expense, after winning European elections in the United Kingdom in May. If, as four opinion polls suggest, UKIP wins the parliamentary seat of Rochester and Strood this week, other Conservative defections may follow.
