Social networks can be a very powerful tools if they are used properly, if you have a good message to send and a better mind to organize the virtual world as needed. I know that the whole idea of social media interaction is treated differently around the globe, some people does not yet understand their meaning. As a old time politician, if you don't see the use of social media stay away of them and put a specialist in communication and internet to do this job for you.
The first important thing a politician must consider when using Twitter is the misinterpretation. The length of the message is essential in Twitter: you must fit everything in only 140 characters. That's all. It does not matter who you are (politician or not), if you want to make youself understood clearly you must write carefully every tweet you send to your followers. Misunderstanding can be translated into votes, usually in losing them. You can lose an entire campaign because you have been ambiguous in several ocasions and the word about it have been spread.
The political issues can be complicated and very hot to the public, but you have to be always objective and very clear. I am not in the position to tell you what to do, but the tweets format should encourage you to take a stand.
Remember that almost anyone can spend their time on Twitter, no matter their place in the world (the only condition is to have access to internet) and what they are using (computers, tablets... and lots and lots of phones). Your interaction with the followers can be done from the same manner: from your office, from your car (but not while driving ), from political and social meetings about hot subjects.
You should know that you are about to interact with people passionate about their opinions, it's very important to keep a clear mind while tweeting and not to heat up while debating with them. You can damage or distroy your political career in such moments.
The last important thing that must be consider: chose very carefully the people you are working with. You may not have always the time to use social media in your advantage and you may use others as relay of your messages on internet. Be sure that you select a person that does not modify your tweets as they want or they seem fit.
