i personally am against capital punishment mainly because of the executions of the innocent, people who were wrongly accused and killed but only found innocent once they were dead. An example of this is the case of derek bentley. there are many other arguments against capital punishment, you can see these on the bbc ethics issues on capital puhnishment.
We do know that many innocent people have been wrongly convicted and executed. People can also be wrongly convicted and sentenced to jail. The difference is, people can be let out of jail, if it is discovered that they have been wrongly convicted, but they cannot be brought back to life, if they have been executed. So capital punishment has the disadvantage of being irreversible. Mistakes cannot be corrected.
Aside from that, the justice system has been known to be unduly harsh, and some people have been executed for relatively minor offenses that did not merit execution.
It has also been suggested that even the most terrible criminals may still have the capacity to improve, and they should be given the chance to do so. There are certainly cases of people who have become great writers or have accomplished other notable accomplishments while in jail. It may be a waste to kill people who still have some capacity for good. Presumably, as long as criminals are kept in jail, they are not a danger to society, so public safety is not harmed by allowing them to live.
All of these are reasonable arguments, although I can equally well produce reasonable arguments in favor of capital punishment. Like most issues, there are two sides.
Many believe that killing someone for killing another is hypocritical.
Actually, opinions on this vary. But the tendency, nowadays, is that a majority of people think that the death penalty is uncivilized. Some arguments against the death penalty is that it is used disproportionately against ethnic minorities (for example, black people in the United States), and that it is irreversible (and there have been many cases where people executed, or people who were planned to be executed, turned out to be innocent). For further arguments, both for and against the death penalty, I suggest you consult the Wikipedia article on "Death penalty".
It depends on the candidate. There is no set liberal or conservative view on the death penalty. There are many liberals who support the death penalty and those who are against it. There are many conservatives who support the death penalty and there are those who oppose it.
Over 1,000 people have been killed since the death penalty was instituted.
many people are but nobody knows how many people
The death penalty is legal in 32 U.S. states. In the United States, 1,386 people have been executed.
The Democratic Party has no one view on the death penalty. There are many Democrats who are against it and many who are pro death penalty. Democrats tend to have a wider range of views within their own party, while Republicans are more unified in their beliefs, however wrong those tend to be.

The UK abolished the death penalty in 1999. The last executions in Britain was in 1964- two men who were hanged for a murder/robbery.
quite a bit of people (YMCMB)
There have been almost 1300 executions via the death penalty in the United States. About 1264 of these executions have been since 1974.
The death penalty is regulated by state governments, and many of them still use it. Texas is notable for it's death penalty system.
