Politics can be fast paced.Within a matter of days an issue arises. alters the political landscape, then is forgotten by most when some new issues surfaces. what people were talking about on monday sometimes seems to b a distant memory when friday comes. News runs faster than ever. however good polling takes time to conduct. Major events can take several days to show up in poll results. The dates when poll was conducted should be noted to determine if current events have had time to affect the numbers of the poll.

Read the following two scenarios...

1. A blog asks its readers to click on a box to show their support of the bill. A total of 5000 participate and there is overwhelming rejection of the bill.

2. A pollin firm randomly calls 1000 registered voters and asks them about their support of the bill. The firm finds that their respondents are more or less evenly split for and against the bill.

Although the first poll has more respondents. they are self selected. The people who would participate are those who have strong opinion.
