Mayawati gave unconditional support to Congress for Presidential Election?

These politicians here in our country are not trustworthy. They say some thing in one place and speak totally different in other place. They are like as the saying goes in our country 'brinjal of a plate' which never have a single face to show. They keep on changing their loyalties as well as their faces according to situations. Today they are giving 'unconditional support' in the name of democracy and cast system where as they are the ones who are airing the cast system in our country. They are doing their politics in the name of casts and advocating against it on paper. I don't think this country would ever come out of cast basis politics ever as long as leaders would not amend their ways of working and would think for the poor public of this country instead of self-centered narrow thinking. I think this is some of these political leaders who are most responsible for the chaotic state of this country.
