Voter Suppression and Political Polls by Charles M. Blow

Polls are used to determine the trend which voters are most likely to follow during an election but these polls are becoming insignificant due to the new voter registration laws which are being put in place especially in vote swinging states such as Pennsylvania. Many likely voters in the swing states intend to vote for President Obama but it is these who are most likely to be excluded from the voting roles due to their ineligibility to vote under the new laws. Both presidential candidates have made numerous visits to swing states in an attempt to get a larger share of votes within these states than their opponents. Moreover, some governors, especially in Florida, have made it harder for former felons to vote and since most of these ex-felons are either of Latino or African American descent who tend to vote Democrat, it means that Obama will most likely lose crucial votes in these states. It is not known exactly how many voters are aware of these new electoral rules due to the fact that not many people follow news about the upcoming elections and the changes which have been made to electoral laws. It is suspected that many people who are expected to vote for their preferred candidates (in this case President Obama) might be turned away due to the fact of their ineligibility. The new election laws have been pushed by Republicans in order to suppress the ability of Democratic voters to vote in large numbers, thus ensuring Republican victories in these states.
