Election Selection - Voters Choice

This morning 23rd April i wake up & I wondered which candidate should i vote? Is there any one who is capable of making a difference? Would my vote make a difference? As i thought about this i realized that i am actually selecting the best among the worst. So, should I vote today or not? If so whom should i vote? Later i decide to vote but whom is still a big question. So, before I head to the polling booth I logged on to the Internet to check what is the track records, education qualification of few of the candidates. Guess what i find on the web? "prisoners" have no right to vote.If this is the case why is a person who has 11 or more criminal records allowed to contest for election. Later I head to the polling booth to cast my vote & find few party workers who are trying to influence every voter they meet as they check their names in the voting list "Sir/Madam please vote for BJP, JDs, congress etc". Finally i enter the polling booth where i was to cast my vote. Now here I find a person a bank employee working there & gave me a paper with some number written on it which was to be handed over to the lady next to him. This lady takes this piece of paper & puts in the ink on my finger. The time finally came when I had to make a choice. Good or bad? well i don't know but yes i did cast my vote. As i head back to my car I realized that my decision of voting a particular candidate was made at the last 2 to 5 mins before I casted my vote.Am I the only guy who made his decision at the last min or are there many more like me? Now, you tell me if you casted your vote, did you make your choice in the last min or you knew whom you wanted to cast your vote well in advance?
