Central and State Political Party
From many decades Karnataka has facing opposite central government issue (ಮಲತಾಯಿ ದೋರಣೆ). I.e. now we have BJP as Political Party is ruling government in Karnataka and congress is the ruling government in Central. Since both the parties are opposite national parties, central congress government is not releasing funds to Karnataka properly.Same issue was faced even in the last elections i.e. Karnataka was ruled by congress (Krishna and Dharam sing as chief ministers) and at central we had BJP government so again it was opposite central government issue (Malathayi Dorane).
Solution for Karnataka
Best solution for this issue to elect regional party i.e BSR in north Karnataka and JDS or KJP in South Karnataka and let both of them lead joint Government (Samyuktha Sarkara) and let them support Central government irrespective of congress or BJP rules central government.
Lets Consider Kaveri Problem. Central Government Congress supported Tamil Nadu. Because we have Tamil Nadu has DMK which is supporting central government from outside. Hence Lets have a regional party in Karnataka.
