Suspense over Karnataka Chief Minister post continued for Day 4 today, with the Congress struggling to bring state unit chief DK Shivakumar on board with the idea of a second term for Siddaramaiah in the top post. Congress chief Mallikarjun Kharge and Rahul Gandhi made two offers to DK Shivakumar at a meeting in Delhi today. But the two-hour meet remained inconclusive, with the top post contender turning down both options, sources said.
